SEMAC-VAT and MSVAT-SPACE Sequence Strategies for Metal Artifact Reduction in 1.5T Magnetic Resonance Imaging

Abstract

SEMAC-VAT (2D) and MSVAT-SPACE (3D) demonstrated a consistent, marked reduction of metal artifacts for different metal implants and offered flexible image contrasts (T1, T2, PD and STIR) with high image quality. These techniques likely will improve the evaluation of postoperative patients with metal implants.
